MEANING: Fluorite is a halide mineral made up of calcium fluoride
Found in Iowa: Yes, it is found on the edges of gray limestone close by Postville in Allmakee county located in the upper northeast. About an hour and 25 min. away from Dubuque to give you a general idea of where Postville is.
How does fluorite form? - Fluorite is formed by the result of violently rising hydrothermal. Hydrothermal is water and melted mineral containing fluorine and calcium. As these solutions erupted towards the earth surface they formed dikes, then they filled fissures and faults.
Hardness of fluorite: 4
Color of fluorite: Light to light- medium green, yellow, purple, pink, blue, brown, and white.
The density of fluorite: anywhere from 3.01-3.25 its average density is 3.13
Luster of fluorite: glassy
Streak of fluorite: white
Chemical formula for this mineral: CaF2
Cleavage/ Fracture: cleavage: 1, all sides – octahedral (even on cubic faces) fracture: conchoidal
The uses for fluorite: Fluorite is used to make some parts in steel making and in the manufacture of hydrofluoric acid. Fluorite used to be used for optical lenses, but it got replaces by synthetic fluorite. It is used as an ornamental stone, and gemstones. You can also see this mineral used to move dye. .
Fluorite's special characteristics: It’s really glassy, and has a big variety of colors, it can have different appearances, it can look like crystals all over the rock, or it can be very smooth and little, its also colorful. It’s name in Latin means, “flow” because its melts easier than other similar minerals. Fluorite also has another name, it can be called Fluorspar. Fluorite is a halide mineral made up of calcium fluoride
Crystal structure for fluorite: Calcium fluoride occurs naturally as the mineral fluorite. Isometric, forms in octahedrons and cubes
great cleavage, hardness and crystal forming’s, it has many different color variety’s including multicolor in which isn't just one color. but many different ones on one thing!
Where fluorite is found in the world: fluorite is found in many places, especially in England, Germany, Mexico, Kentucky, Illinois, and in the United states!
What is fluorite made of? Is a halide mineral composed of calcium fluoride CaF2.
